List of Array to datatable

Hi,

I have a class

public class AppUpdator
{
public string ApplicationName { get; set; }
public Version CurrentVersion { get; set; }
public Version InstalledVersion { get; set; }
public DateTime ReleaseDate { get; set; }
public StringBuilder Description { get; set; }
public List filenames = new List();
}
public struct FileNames
{
public string FileName { get; set; }
public string DestinationFolder { get; set; }
public byte FileSize { get; set; }
public enum FileOperation
{
Copy,
Unzip,
Delete,
Execute
}
public FileOperation Operation { get; set; }
public string DownloadURL { get; set; }
}

I use Generic to convert list to Datatable

public DataTable CreateDataTable(IEnumerable list)
{
Type type = typeof(T);
var properties = type.GetProperties();
DataTable dataTable = new DataTable();
foreach (PropertyInfo info in properties)
{
dataTable.Columns.Add(new DataColumn(info.Name, Nullable.GetUnderlyingType(info.PropertyType) ?? info.PropertyType));
}
foreach (T entity in list)
{
object[] values = new object[properties.Length];
for (int i = 0; i < properties.Length; i++)
{
values[i] = properties[i].GetValue(entity);
}
dataTable.Rows.Add(values);
}
return dataTable;
}

But datatable doesnot return the list of files (as highlighted), it excludes the List variable and return only 5 columns to datatable.

How to include that

Accepted answer
Try to change
From
public List filenames = new List();
To
public FileNames[] = new FileNames[x];
//where x is array length

Thank you all for your reply!!

Hello Amit
I changed my code, as you said and it works perfectly. But when bind this datatable with datagrid, the filename column was not shown there.

@Rafnas
I am passing collection of the main class AppUpdator

whre are you calling CreateDataTable function,
you have to call this function as below

DataTable dt= CreateDataTable(filenames);

then you can see allthe filenames in datatable dt
